Are things online cheaper than offline

for me it is.the markup in my town is ridiculous. and thanks to the internet we're no longer at their mercy.

Depends upon the item hehehehe

Sometimes the price is cheap online if they hold a massive discount up to 90%.

Not always. If you live in a large city you can often find better deals locally, but you need to visit a lot of shops and not take your time into account. The main problem with items bought online is that when a failure happens it is difficult to activate the legal guarantee of the seller (2 years in the EU), so I only buy very cheap items online.

I have been shopping online, and the price on the Internet is much cheaper than the price of the store.

Looks like you might save more online, because it can go direct from the warehouse to you and skip the middle man of retail.
